what do you mean by not working? is there any exception?
if I remember correctly, IIS is not case sensitive.
can you show me the url of your website to see what wrong with url rewriting?

If your web application stores session data in-process which is the default behavior,
the process will be restarted when this process is not instability, then your session will be lost.
some files modified can be lead to restart process.
such as Global.asax, Web.config, bin etc.
Anti-virus software scanning .config files also can lead to restart process.
my english is not very well, i hope it'll help you.

ASP.NET - C# (C Sharp) – SQL Server 2008
Hi!
I’ve got a master table and a child table. The master table has a nullable column called ReferenceID and in some cases it should be NULL, but when it’s null in a record, I get an error while going to Edit mode of DetailsView.
DB Tables:
MasterTable [Columns: MasterTableID (PK), Name, ReferenceID (FK)(Nullable)]<br />
ReferenceTable [Columns: ReferenceID (PK), Reference]<br />
<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False">
<Fields>
<asp:BoundField DataField="MasterTableID" HeaderText="MasterTableID"/>
<asp:BoundField DataField="Name" HeaderText="Name"/>
<asp:TemplateField HeaderText="Reference" SortExpression="Reference">
<EditItemTemplate>
<asp:DropDownList ID="DropDownList_Reference" runat="server"
DataSourceID="ObjectDataSource_ReferenceTable" DataTextField="Reference"
DataValueField="ReferenceID" SelectedValue='<%# Bind("ReferenceID") %>'>
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="LabelReference" runat="server"
Text='<%# Bind("Reference") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:CommandField ShowDeleteButton="True" ShowEditButton="True" />
</Fields>
</asp:DetailsView>
Select Queries:
Select MasterTable.*, ReferenceTable.Reference
From MasterTable INNER JOIN
ReferenceTable ON MasterTable.ReferenceID = ReferenceTable.ReferenceID
Select * from ReferenceTable
In Read Only mode all everything is OK, but when I click on Edit and Postback happens, I get the following error:
'DropDownList_Reference ' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value
It means that in MasterTable, the ReferenceID shouldn’t be NULL, but it should be in some cases.
I’d appreciate if someone give me a solution.Kardo

Change your database schema, you can't have a foreign key that is null.

Hi,
I have a problem, i have a gridview populated with items and in the pager i have controls for previous and next and a dropdownlist that shows the total number of pages. I also have a search function to search for item.
if i for exemple search for *egg* i get a number of results and the ddl is populated with total number of pages for the searchterm. but if i click on the button for "next" the search result disapear and i get all the pages back (because of the postback) but how do i do to keep the state of the ´search so that i can use the next and previous buttons and the ddl listing of pages, depending on the search?
I have never used viewstate so if someone can explain it well for me i would appreciate it very much! How to write the code and implement it.
I use nhibernate and custom binding/paging

You need to persist the search criteria in some manner and use it when requering the database. If you are using a textbox to eneter search criteria then enable viewstate and retrieve it's value before querying the database. Along with the page and number fo rows to retrieve of cource.
The builtin support for paging in the datagrid should handle this for you though.

Then I suggest you stop what you are doing and learn more about ASP.NET.
Thommie.h wrote: SO i need 2 queries against the database?
No. I suggest you also spend some time understanding SQL queries before continuing.
Understanding the tools and technology you are attempting to use will save you (and us) headaches and fustration.

you are not helping me here, if you can explain a little as i asked from the beginning it would have helped or hint me somewhere.

And what good would it do? You don't understand the concepts, tools, or technology.
You have all the help and hints you need. Go read.

hi,
you can store the search parameters into viewstate
when you click on the button for "next", you needs rebind the data.
you can also store the search parameters and page information in url like this:
http://search.aspx?parameter=egg&page=1
my english is not very well, can u teach me english ? haha~

hi,
Request.UrlReferrer gets information about the URL of the client's previous request that linked to the current URL.
If user enter the URL manually , then value of Request.UrlReferrer is null
Other method : Request.ServerViables["http_referer"]
if you have any questions, please contact me

Hi everyone,
Can anyone give me some idea how can I retrieve information when the user clicked on a specific link without opening a new web page? The information is stored in the database which is through web service.
For example, when the user click on a specific link, e.g the date 28 February 2010, the datagrid will display the information on 28 February 2010.
thank you.
